DEVICE FOR OPERATING THE SHAKING-SHOES OF GRAlN-SCOURERS, 8L0.

SPECIFIOATION forming part of Letters Patent No. 436,581, datedSeptember 16,1890.

Application filed June 4:, 1888- Serial No. 275,935- (No model.) I

- To all whom it may concern.-

from the main driving-shaft.

The object of my invention is to provide a simple connection whereby theshaking-shoe is operated directly from the main shaft.

The invention consists of the improvements which will be hereinafterfully set forth, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of agrain-scourer provided with my improved shoe-actuating device.

Fig. 2 is a vertical longitudinal section of a portion of the vibratingshoe, showing the plate to which the end of the connecting-strap issecured. Fig. 3 is a top plan view of said plate. Fig. 4 is an enlargedside elevation of the actuating device. Fig. 5 is a cross-section of theoscillating quadrant and its supporting-bracket. Fig. 6 is across-section of the eccentric and a portion of the connecting-strap.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frameof a grainscourer.

B is the casing inclosing the revolving scouring drum or cylinder, and Gis the windtrunk.

cl is the horizontal driving-shaft arranged lengthwise of the machineand upon which the scouring drum is mounted. The driving shaft cl isjournaled in bearings arranged in the end frames ofthe machine.

E represents the shaking shoe arranged above the casing B and supportedupon flexible arms or bars a, secured with their lower ends to the frameA. The shaking-shoe E contains the sieves 0r screens and vibrates in aplane parallel with the driving-shaft d, or in the longitudinaldirection thereof.

F represents an eccentric mounted on the driving-shaft (Z, and F is theeccentric strap or yoke provided on its upper side with a lug or car f.

G represents an oscillating quadrant pivoted to a bifurcated bracket g,secured to the upper rear cross-piece of the frame A above the shaft 01and swinging in the same plane as the shaking-shoe.

H is a metallic connecting-strap secured at its lower end to the lug fof the eccentricyoke F and at its upper end to a metallic plate I,secured to the bottom of the shakingshoe by screws 1'. The plate I isprovided on its inner side with a projecting rim or lug t", which fitsin a circular recess formed in the bottom of the shaking-shoe andassists in rigidly securing the plate to the shoe. The connecting-strapH passes over the curved face of the quadrant G and is secured theretoby rivets or otherwise, so as to move therewith. The eccentric F impartsa reciprocating motion to the connecting-strap H, and the latter in turntransmits a similar movement to the shaking'screen in the longitudinaldirection of the driving-shaft (l. The lower portion of theconnecting-strap H adjacent to the lug f is preferably bent or twistedin line with said lug, as shown, so that the strap may yield laterallyand follow the movements of the eccentricF without straining or bendingthe strap.

The connecting-strap consists of a single strip of metal havingsufficient flexibility to permit its being bent around the quadrant H,and is free from any joint, which are liable to become worn.

This construction forms a simple and cheap connecting device fortransmitting motion to the shaking-screen directly from thedrivingshaft. It does away with the usual countershaft, pulleys, andbelt, and reciprocates the shoe with a less violent motion than thecocentric andj connecting rod heretofore employed.

My improved device is shown as applied to the shaking-shoe of agrain-scourer; but it is obvious that it may be used in other similarmachines in which the shaking-shoe is arranged above the driving-shaft.

I claim as my invention- The combination, with the stationarysupporting-frame and the horizontal drivingshaft jonrnaled therein, of ashaking-shoe supported upon the main frame above the 5 driving-shaft, aneccentric F, mounted on the driving-shaft and having a yoke providedWith a lug f, an oscillating quadrant G, pivoted to the main frame abovethe drivingshaft, and a metallic connecting-strap H, run- IO ning oversaid quadrant and secured with its upper end to the shaking-shoe andhaving its lower end twisted in line with the lug f of the eccentric andsecured to the same, substan: tially as set forth.

WVitness my hand this 29th day of May, 1888. I5
